Abstract

Fish biodiversity studies were undertaken from January 2012 to December 2012 to census commercially important fishes in the Sindphana Dam. The present paper deals with the variety and abundance of freshwater fishes in the Sindphana Dam near Shirur Kasar Dist. Beed [M.S] India. The results of the present investigation reveal the occurrence of 44 fish species belonging to 7 orders, 15 families, and 26 genera. Among the collected species order Cypriniformes was most dominant constituting 50% followed by order Siluriformes constituting 18%, order Perciformesconstituting 18 %, orders Osteoglossiformesand Synbranchiformes constituting 5% and orders Mugiliformesand Beloniformes constituting 2 %of the total fish species. Fish biodiversity indices species richness 44 in the total number of species (N0), 3.73 in Margalef’s index (R1), and 0.97 in the Menhinick index (R2). Species diversity was 0.47 in the Simpson index (), 1.16 in the Shannon-Weiner index (H’), 2.98 in abundant species (N1), and 2.80 in very abundant species (N2). Species evenness was 0.42 in (E1), 0.21 in (E2), 0.17 in (E3), 0.95 in (E4), and 0.97 in (E5). Bangladesh J. Zool. 51(2): 155-164, 2023

印度马哈拉施特拉邦比德县希鲁尔-卡萨尔附近辛德法纳河大坝的鱼类生物多样性现状

2012 年 1 月至 2012 年 12 月期间开展了鱼类生物多样性研究，以普查 Sindphana 大坝中的重要商业鱼类。本文论述了印度比德[M.S] Shirur Kasar 区附近 Sindphana 大坝淡水鱼类的种类和数量。调查结果显示，该水域有 44 种鱼类，隶属于 7 目 15 科 26 属。在采集到的物种中，鲤形目占优势，占 50%，其次是丝形目，占 18%，鲈形目，占 18%，骨舌形目和合支形目，占 5%，鲻形目和贝隆形目，占 2%。鱼类生物多样性指数物种丰富度（N0）为 44，Margalef 指数（R1）为 3.73，Menhinick 指数（R2）为 0.97。物种多样性的辛普森指数（）为 0.47，香农-韦纳指数（H'）为 1.16，丰富物种（N1）为 2.98，极丰富物种（N2）为 2.80。物种均匀度（E1）为 0.42，（E2）为 0.21，（E3）为 0.17，（E4）为 0.95，（E5）为 0.97。孟加拉国动物学报》。51(2):155-164, 2023
